You are right -- hand brake is mechanical. Sorry.

As has been pointed out by Samurai and mdsaab if you manage to engage P while in motion, there is a safety which stops engagement until the vehicle stops. If you manage to actually get P engagement while in motion damage to the gearbox is almost guaranteed.

So does this mean MT is safer than AT? You can reasonably drive with engine breaking in MT, while in AT if there is a brake fail you either have an accident or break your gearbox?

Good point there about the dual mast cylinders. However, i'd disagree with the 0.01 in a million -- especially if we are talking about brake fluid overheating (due to riding the brakes etc), which would happen symmetrically and therefore on both circuits.

You might have had a good experience with the pure DOT4/DOT5 in your Esteem, though in this case gou's car could have been (for example) DOT3 with a bit of humidity in the system -- which would change things dramatically. So i still wouldn't rule that out.

Yes, this is really strange! Sgiitk has mentioned the reason why.
